Struct V2ChunkKeyEncoding 

pub struct V2ChunkKeyEncoding { /* private fields */ }

A v2 chunk key encoding.

The identifier for chunk with at least one dimension is formed by concatenating for each dimension:

• the ASCII decimal string representation of the chunk index within that dimension, followed by
• the separator character, except that it is omitted for the last dimension.

See https://zarr-specs.readthedocs.io/en/latest/v3/chunk-key-encodings/v2/index.html.
